Improvement in seal-locks



catches, as herein described, can beinserted through the disks, without their being gated for that purpose, but that, when once inserted, the least movement of cit-her ofthe disks prevents its movement in an opposite direction.

M'y lock may be marked with a letter, S, fig. 1, or other sign, by which to refer to a record in cipher of its combination,

Having thus described my invention,

What I claim, is-

1. A lock, having a chamber or receptacle for the insertion of a stamp or similar seal, said chamber being so arranged that it shall be securely closed by the closing of the door or lid to which the catch is attached, to prevent yaccess to the seal, and having its sliding bolt so constructed and arranged in relation to the seal, that the movement of the bolt in unfastening the lock shall tear or otherwise cancel said seal, substantia-ily as herein described.

2. The bolt H, having. a series `of spring catches, 71, pi-voted thereto, when constructed and arranged substantially as and for the purpose set forth.

3. The combination ofthe bolt H, having a series of spring,r catches,h, pivoted thereto, with loosely-rotating disks c, when constructed and arranged to operate substantially as and for the purpose set forth.

4. The combination of the catch b andthe sliding locking-bolt C, pivoted with thespring jaws L, when constructed and arranged to operate substantially as and for -the purpose set forth.
